PACKING-Tool..

SPECIFICATION forming' part 0f Letters Patent No. 47 3,008, dated April 19, 18x92. Application filed l.Tuly 15, 1891. Serial 110.399,560. (No model.)

.To a/ZZ whom t may concern:

Be it known that I, JOHN F. LYNCH, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Packing-Tools; and I do declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this v specification.

The object of my invention is to provide a tool which may be used for packing the tubes of condensers or similar articleswhere a number of tubes are secured in a tubesheet.

In the accompanying drawings, Figure lis a perspective View of a tool constructed in accordance with my invention. Fig. 2 is a longitudinal section of the same, the packing-cord vbeing wrapped in position on the mandrel or former. Fig. 3 is a similar view showing the cordbeing pressed into position around the tube. Fig. 4 is a sectional plan view on the lin-e x Fig. 2; and Fig. 5 is a sectional plan v iew on the line y y, Fig. 2.

In packing. the tubes of condensers it isv usual to employ cord, the successive layers or windings being separately forced down into the packing-box, the operation requiring much time and care to produce a good joint.

In carrying out my invention I employ a tool on which the cord is first Wound and then pressed into the packing-box at one operation. 1

`A represents a hollow stem having at one of its ends a solid head a, and guided Within this head is a former or mandrel B, from -Which projects avpin b, running in a slot c in the stem A, the two parts A B being normally forced apart by the action of a compressionspringe within the stem A. The main body of the mandrel or former B is adapted to t within the hollow stem A and projects therefrom when the spring is acting a sufficient vdistance to hold enough packing-cord to fill the packing-box D, through which the tube passes. The outer end Z9 of the mandrel is reduced in diameter in order that it may be fitted within the tube to be packed, and is the'end of the tube,

preferably provided with a conical pointed end b2 for convenience in inserting itv in the end of such tube, the tocl being pressed into the tube until the shoulder b3 abuts against Surrounding the stem A is a sleeve E, provided with a longitudinal. slot e, in which ts the pin b, projecting from the mandrel B. A

In operation the packing-cord is coiled around the projecting portion of the mandrel B, the sleeve E being held up in the position f show n in l and 2 bythe engagement of the pin b With a recess cin the sleeve. After.

the windin g is completed the sleeve is slipped down over the packing-cord in order to keep the coils in proper position. The end of the mandrel is then inserted in l.the end of the tube to be packed until the shoulder b3 comes into conta-ct with the end of the tube to be packed. Then bythe use of sufficient pressure on the head a, or by a sharp hammer-blow the coils of packing-cord are forced from the mandrel and around thetube -by the end of the stem A.

If desired, the protectingsleeve E may be v omitted, as it only serves to prevent .the coils from being forced outward. Its use, however, is preferred, and I have for that reason described it. l

`Having thus described my invention, I claim and desire to secure by Letters Patentl. `A packing-tool comprising a windingsurface for the packing material and a headed stem 'or sleeve adapted to fit thereon, whereby the packing on the Winding-surface may be forced around the tube being packed, substantially as set forth.

2. A packing-tool comprising a windingmandrel for the packing material, a hollow stem in which said mandrel is guided, and a protecting-sleeve adapted to tit Vover the coils of packing material, substantially as set forth.

3. A-packing-toolv comprising a Winding? surface or mandrel for the packing material, a headed and slotted stem in which said mandrel is guided, and a projecting pin on said mandrel, adapted to the slotted portion of the stem, substantially as set forth.

4. A packing-tool comprising a Winding surface or mandrel for the packing material, aslotted-stem in which such mandrel is guided,` a slotted protecting-sleeve on said stem, and

IOO

a projecting pin on said mandrel, adapted to guiding said niandrei, substantially as speci- .the slotted portions of said stem and sleeve, fied.

4 IO substantially as specified. In testimony whereof I affix my signatn re in 5. A tube-packing tool oomprlsing awindpresence of two Witnesses. 5 ing-mandrel having a Winding-surface for the packing material and a reduced end portion Witnesses: adapted to it within the tube to be packed, DAVID S.
